摘要
在机械制造各行业的工艺过程中广泛应用着各种不同的，用以固定加工对象，使之占有正确位置，以便接受施工的一种工艺装备，统称为夹具。因此，无论是在机械加工，装配，检验，还是在焊接，热处理等冷，热工艺中，以及运输工作中都大量采用夹具。但在机械加工中应用最为广泛的是金属切削机床上使用的夹具，我们称其为机床夹具。它在保证产品优质，高产，低成本，充分发挥现有设备的潜力，以便工人掌握复杂或精密零件加工技术，以减轻繁重的体力劳动等诸方面起着巨大的作用。因此，机床夹具的设计和使用是促进生产迅速发展的重要工艺措施之一。为此，在本次设计时，选择了机床夹具设计。
本文主要围绕机床钻孔夹具设计为中心。用以钻发动机连杆零件，首先通过参观实习让我们对夹具设计有了初步的了解，特别是对盖板式钻模夹具设计的了解更为深刻。然后，在导师的指导下，对夹具设计方案进行分析和选择。选定方案后，。通过查阅相关夹具设计书籍和相关图例在钻孔夹具设计过程中，。在查阅了相关文献后完成外文翻译。参考相关资料完成夹具的总体设计。

Abstract
Machinery manufacturing industries in the process of awidevariety of applications for processing a fixed object, so that it occupies the correct position in order to receive a construction technology and equipment, collectively referred to as the fixture. Therefore,whether in the machinery processing, assembly, testing, or inwelding, heat treatment, such as cold, heat process, and transport are a lot ofwork in a fixture. But in machining is the mostwidely used metal-cutting machine tools for use on the fixture,we called for the machine tool fixture. It guarantees high-quality products, high-yield, low-cost, bring into full play the potential of existing equipment, so thatworkers have complicated or sophisticated parts processing technologies, to reduce the heavy physical labors, and other aspects play a huge role. Therefore, the fixture of the machine is designed to promote the production and use of the rapid development of one of the important process.
This article mainly revolves the engine bed drill hole jig design is a center. With drills the azimuth training gear shell, first let us through thevisit practice have the preliminary understanding to the jig design,was specially more profound to the lap type jig jig design's understanding. Then, under teacher's instruction, carries on the analysis and the choice to the jig design proposal. After designating the plan. Through consult related jig design books and related chart of symbols in drill hole jig design process. After having consulted the related literature completes the foreign language translation. Refers to the correlation data to complete jig's system design.
